Used as a coupling agent to improve adhesion between organic polymers and inorganic materials, especially in composite systems. Enhances dispersion of fillers in plastics and rubber, leading to better mechanical properties and processability. Commonly applied in sealants, adhesives, and coatings to increase water resistance and durability. Also used in paint formulations to reduce viscosity and improve pigment wetting. Effective in mineral-filled polyolefins to improve impact strength and elongation.
